This is a casual-tower defense game. Players randomly create multiple gems in each level and use one of the gems as a defense tower to attack monsters, and the others turn into stones to block monsters. The monsters will advance along the designated waypoints one by one, and the player forms a maze through towers and stones to increase the path for the monsters to reach the base. The level ends when the monster is defeated or the final path is reached. There are a total of 50 levels in the challenge mode. After completing 50 levels, the game is won. After the game is won, you can continue to challenge the endless mode until the HP returns to zero. ## Key features - Random gem creation for defense towers - Strategic maze building - 50 challenging levels - Endless mode - Monster path blocking ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | 4x Speed | $0.99 | one-time | | 1300 Gems | $12.99 | one-time | | 100 Gems | $0.99 | one-time | | 300 Gems | $2.99 | one-time | | 10000 Gems | $99.99 | one-time | | 600 Gems | $5.99 | one-time | | 5000 Gems | $59.99 | one-time | ## Recent user reviews (10 of 16) All indexed reviews: https://appshunter.io/ios/app/gemtd-mobile/id6449473701/reviews.md ### 1/5 — Ne marche pas *2025-11-30, version 1.0.2* Se que je trouve ça bizarre le jeux marche pas mes on peut faire des achat … ### 4/5 — Fun but bugged *2025-04-27* I finally made a maze that got me past level 62 and it every time I get to level 67, the things just run in circles and make it impossible for me to lose. So I have to restart a new game and lose out on my high score. Which would probably be around 1.9M ### 2/5 — Crashes on wave 58 *2025-04-02* I enjoyed GemTD in Dota 2 arcade. Wards as towers was neat. Secret towers were even more interesting, allowing several additional hours of game play. iOS version is okay. Towers are boring and waves can also be. No more secret towers. Pay to upgrade abilities. It works, though feels very shallow. ### 1/5 — Crashes on wave 58 *2025-01-21* Can’t find secret towers like the classic Dora 2 arcade version. It got boring without the secret towers. ### 4/5 — Lot of potential! *2024-12-27, version 1.0.2* The Dota version is a classic and this mobile game reflects it well, but as a mobile game it still needs lots of UI adaptations, as is today is like a pc game ported to a phone. Looking forward for the next updates! ### 2/5 — Crashes on wave 58 *2024-10-31* Can’t find secret towers yet. Will rate 4 star if their still there. Having problems when reaching wave 58. The game crashes and I have 1.09 million points. I’ve gotten more points earlier in the game. ### 4/5 — It’s a little ruined but still good *2024-09-11* I used to love this game but the extra stones on the outside of the checkpoints completely ruin it. You are unable to develop a maze that incorporates some of the checkpoints and not others. If you were to remove the extra stones on the outside then it would completely change the game and make it a lot more entertaining. ### 1/5 — Spyware *2024-08-13* At 1.17 gb, it’s clear this game is an intrusive software, skimming your data. Avoid. ### 5/5 — GemTD now PokerTD?! *2024-05-10* This is awesome! Love it and great job. While digging into old TD’s can you use these same mechanics, even the same map to remake PokerTD (solo)??? If you were able to recreate PTD on this level it would be unreal! Thank you for bringing this game back! ### 1/5 — imposible de jouer *2024-01-27, version 1.0.2* le probleme imposible de placer qoui se sois :( ## Frequently asked questions about GemTD Mobile ### What is the gameplay like in GemTD Mobile?
